Description

Front-mounted filtering device for oil-water separation

Technical Field

The utility model relates to the technical field of kitchen residue treatment, in particular to a pre-filter device for oil-water separation.

Background

The sewage discharged by the catering industry contains a large amount of grease, and pollutants which are difficult to decompose can be caused to the environment when the sewage is directly discharged into an underground sewage system, so that the oil-water separation is generally carried out at the direct sewage discharge position in the catering industry at present, on one hand, the grease discharged into the environment is reduced, and on the other hand, the grease can be recycled.

The oil-water separator commonly used at present is an oil-water separator, and the working principle of the device is as follows: the oil and water are incompatible, the oil and water can be layered after standing, the oil and water are layered in the separation chamber after the oil-containing wastewater enters the separation chamber from the water inlet, after the separation chamber is full of fluid, floating grease is accumulated on the upper part of the separation chamber, most of the middle part is water, the lower part is provided with partial deposition pollutants, along with the increase of water inflow, the more the grease on the upper part is stored, when the grease is accumulated to a certain degree, the grease discharging valve is opened, and the grease is discharged into the grease collector. Meanwhile, after the separation chamber is filled with water, a large amount of separated sewage is discharged from the water outlet.

Although the oil-water separator can separate oil from water in sewage, the oil-water separator also has some defects: because the components in the sewage discharged from the catering industry are complex, after the sewage is separated by an oil-water separator without pretreatment, the upper layer of the floating oil in the separating chamber is provided with a plurality of suspended matters with smaller density and other impurities, so that the impurities in the separated grease are too much; secondly, too much residue is deposited, and the drain valve is difficult to drain, which can cause blockage and difficulty in cleaning the separator.

At present, devices are arranged outside the separator for pretreatment in some catering industries, special equipment is needed, the occupied area is large, and environmental pollution is also possibly caused. Thus, there is a need for an environmentally friendly, non-occupied, pre-wastewater treatment oil-water separator.
